Oil Pressure

[cdan34]

This question is about the start up of a rebuilt flathead with all the good hi performance stuff. Trying to help my freind with this project, we can't seem to get oil pressure. It has a Melling helical gear oil pump and Motor City Flathead out side oil filter. When the engine was turned over the gage didn't register oil pressure. When we took the filter off and turned the engine, the volumn of oil coming out was not much! Everything inside the engine was put together right, the gears in the oil pump were not lubed with heavy oil, could this be the problem? and it's not picking up the oil from pan? Has this happened to anybody else? any suggestions?

Thanks much
Chuck

There have been many reported problems with the Motor City setup not priming. May be your problem. I have no idea what the remedy is. Maybe making sure that the filter is full of oil before it's installed?
I'm sure someone will have the answer for you

The first thing I would do through that MCF oil system to h---. Of course I would have used it in the first place. BUT, seeing that you have it all together get, beg, borrow or steel, a pressure tank, hook it up to where the sender unit screws in. Pressurize 3-4 gt's of oil into the system. That will prime the whole system, it will fill the oil filter and the whole engine. It will have oil pressure as soon as you start it. If it don't there is something wrong. Walt

you said you rebuilt the engine is the plug behind the cam gear installed?

Do you have filter lines installed correctly? If reversed the filter won't fill of flow oil.
